Kim Nguyen and Nguyen's twin brother Khoa spent about two hours at Changi Prison visiting the condemned Melbourne man, who is scheduled to be hanged on December 2nd.
Nguyen, 25, was arrested in 2002 at Singapore's Changi airport caarrying almost 400 grams of heroin.
After being convicted, he lost his appeal and had all appeals for clemency from Canberra turned down.
Now there appears almost no chance that Nguyen will avoid the gallows.
Prime Minister John Howard, who has led repeated, last minute calls for clemency, has conceded that Canberra has now exhausted all practical diplomatic avenues.
"I do not believe the government of Singapore will change its position. I have to say that and I owe it to Mr Nguyen's family, I owe it to the Australian people to give an honest opinion, Mr Howard told reporters in the Pakistan capital Islamabad.
Howard ruled out the chances of a final legal appeal, saying the International Court of Justice had no jurisdiction as Singapore was doing nothing illegal.
Despite that bleak assessment, Victoria state Attorney General Rob Hulls is travelling to Singapore to press Nguyen's case once again.
Accompanied by Australia's High Commissioner to Singapore Miles Kupa, Hull's is set to meet with Singapore's Senior Minister of State for Law and Home Affairs Ho Peng Kee on Thrusday.
Mr. Ho, however, is a relatively junior member of Singapore's political establishment. It is understood that Mrs Nguyen will be allowed hour-long visits on Thursday, Friday and next Monday, with longer visits in the final three days before the December 2 dawn hanging.
Authorities at Changi Prison have declined to comment on whether Mrs Nguyen would be permitted to see her son this weekend, which is likely to be his last.
A Singapore woman, Pauline Oi Chen Ni, wrote arguing strongly that no clemency should be shown to Nguyen. "Australia, in indluging in mob hysterics (and maybe a false sense of moral superiority) has chosen to ignore Singapore's sovereignty and the laws governing our land and people," Mrs Oi said.

What do you think? I would be interested to hear everyone's opinions on this
If you are going to deal in drugs then you have to suffer the consequences. Australians, or anyone for that matter should know better. I think we should stay out of it. The same thing has happened in Bali and the government pretty much left two aussie girls to fend for themselves. It wasn't heroin. In one case some weed and in the other two estacy tablets. Schapelle Corby is imprisoned in Bali for 20 years for weed. She was lucky to escape the death penalty. Michelle Leslie served three months for having two estacy tablets on her at a party in Bali.
